Runtime.ImportModuleError: Unable to import module 'vc__handler__python' if the root folder is set one level above the server folder on vercel
I recently watched video “Deploy Django Project on Vercel with Supabase PostgreSQL: Step by Step Guide”. I followed this video step by step, and my project was really deployed. But it deployed if i picked my folder python_server/ as root directory. But I need to select the folder one level up as root directory. I have project structure like this: Project/ ├── python_server/ │ ├── __init__.py │ ├── mysite/ │ │ ├── __init__.py │ │ ├── settings.py │ │ ├── urls.py │ │ ├── wsgi.py │ ├── manage.py │ ├── gif_service/ │ │ ├── templates │ │ ├── views.py │ │ ├── urls.py │ ├── static │ ├── staticfiles ├── public ├── views ├── js_server I copied my static files from /public and views from /views to /python_server. And I picked /python_server as folder root. It’s works well for vercel. But it’s not good for me. Because I use views from /views and static files from /public for both server: Express server and Django. And so It’s not good practice to have copy of that static and html files. So I need to deploy vercel not with python_server/ as root folder, but with Project/ as root folder. I really tried … -
Not able to select database for database queries in django
I'm trying to direct my read queries to my read replica in a production setup. Django allows defining multiple databases, so I added two databases like: DATABASES = { "default": { "NAME": "ironbank", "ENGINE": "django_postgrespool2", "USER": "postgres", "PASSWORD": os.getenv("DATABASE_PASSWORD", "postgres"), "HOST": os.getenv("DATABASE_HOST", "localhost"), "PORT": os.getenv("DATABASE_PORT", "5432"), "CONN_MAX_AGE": 0, }, "replica": { "NAME": "ironbank_replica", "ENGINE": "django_postgrespool2", "USER": "postgres", "PASSWORD": os.getenv("DATABASE_PASSWORD", "postgres"), "HOST": os.getenv("REPLICA_DATABASE_HOST", "localhost"), "PORT": os.getenv("REPLICA_DATABASE_PORT", "5432"), "TEST": { "MIRROR": "default", }, "CONN_MAX_AGE": 0, }, } Here I'm using two different databases to test it setup locally. I also have a database router configured as file: settings.py DATABASE_ROUTERS = ["ironbank.router.PrimaryReplicaRouter"] --- file: ironbank/router/PrimaryReplicaRouter.py class PrimaryReplicaRouter: @staticmethod def db_for_read(model, **hints): """ Reads go to a randomly-chosen replica.

is it possible to use django-push-notifications[FCM] for both android/ios? (if both apps configured in firebase)
I want to use django-push-notifications library for push notifications. My mobile app part configured firebase for both android and ios. In library's documentations they separated logic and configuration of gcm and apns devices. Can I use just GCMDevice for both android and ios devices (to save them, send message) as it is already configured in firebase? Or should I configure apns in django also as it is mentioned in documentation from firebase_admin import auth # Initialize the default app (either use `GOOGLE_APPLICATION_CREDENTIALS` environment variable, or pass a firebase_admin.credentials.Certificate instance) default_app = firebase_admin.initialize_app() PUSH_NOTIFICATIONS_SETTINGS = { "APNS_CERTIFICATE": "/path/to/your/certificate.pem", "APNS_TOPIC": "com.example.push_test", "WNS_PACKAGE_SECURITY_ID": "[your package security id, e.g: 'ms-app://e-3-4-6234...']", "WNS_SECRET_KEY": "[your app secret key, e.g.: 'KDiejnLKDUWodsjmewuSZkk']", "WP_PRIVATE_KEY": "/path/to/your/private.pem", "WP_CLAIMS": {'sub': "mailto:development@example.com"} } If so, how to do it properly? -

Static not loaded when django project deployed
I'm trying to deply my django site, and I did to my ip address, but when I load page online it doesn't load static files. I tried changing different settings on a server and on django files, but I'm out of ideas. I would appreciate a pair of fresh eyes. for sites-available I did this: sudo nano /etc/nginx/sites-available/django-site Output: server { listen 80; server_name xx.xx.xxx.xx; #my ip address location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /home/muser/django-site/staticfiles/; } location / { include proxy_params; proxy_pass http://unix:/run/gunicorn.sock; } } this is settings.py STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static'), ] #media MEDIA_URL = 'media/' MEDIA_ROOT = BASE_DIR / 'media' It might be that this is all correct, but it might be that urls aren't set up properly. So please see urls.py urlpatterns = i18n_patterns( path(_('admin/'), admin.site.urls), path('rosetta/', include('rosetta.urls')), path('', include('my_app.urls', namespace='my_app')), ) if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT) urlpatterns += static(settings.STATIC_URL,document_root=settings.STATIC_ROOT) Any ideas what I did wrong?

ReportLab Encoding Issue When Drawing Translated Text in Django
I encountered an issue when using drawString in ReportLab to draw text in the Czech language after translating the text with Django. I've set the font to Arial, which supports the necessary characters, and noticed the following behavior: When I draw a string directly like this: t = "vůči" self.canvas.drawString(10, 10, t) The text is rendered correctly. However, when I try to draw a translated string like this: from django.utils.translation import gettext as _ t = _("towards") self.canvas.drawString(10, 10, t) The text is rendered incorrectly, showing black rectangles instead of the expected characters, indicating that the characters are not being recognized. Does anyone know why this is happening and how to fix it? -

Trying to create a generic HTML template that renders a set of questions under topic headings based on context from views.py
I have several areas, i.e. Leadership, operations, etc., each of which has a set of topics and questions associated with it. Leadership, for example, has 3 topics, each with a different set and number of questions. I am trying to create a general questions.html template where the views.py can then fit with the specific area, topics, questions, etc. for that area. I provide the topics, separate question sets for each topic via context when rendering the page for that area. I am trying to avoid hardcoding each page by looping through each topic and using the question set for that topic. I tested the code by hardcoding 1 question set and seeing if the table render properly, and it does except of course the questions are repeated under each topic. However, when I set the outer loop to loop through the topics with each unique questions set using variables, none of the questions appear. The page just renders the topics with no errors.

Django ORM efficient way for annotating True on first occurrences of field
I have a situation where we have some logic that sorts a patient_journey queryset (table) by some heuristics. A patient_journey has a FK to a patient. I now need an efficient way of setting True for the first occurrence of a patient_journey for a given patient, false otherwise. The first heuristinc is patient_id so the queryset will already by grouped by patient. The algorithm is v straight forward & should be fast, yet I'm stuck at trying to get something <1s. I've tried using distinct and checking for existence, however that's adding 1-2s. I've tried using a subquery with [:1] & test on id, but that's even worse around 3-5s extra. def annotate_primary( *, qs: 'PatientJourneyQuerySet' # noqa ) -> 'PatientJourneyQuerySet': # noqa """ Constraints: -------------- Exactly One non-global primary journey per patient Annotations: ------------ is_primary_:Bool, is the primary_journey for a patient """ from patient_journey.models import PatientJourney qs = get_sorted_for_primary_journey_qs(qs=qs) # cost until now is around 0.17s # using distinct on patient_id & checking if id is in there adds around 1.5-2s # looking for something faster, i.e. this shoiuld be a straight forward scan. qs = qs.annotate( # True for first occurrence of a `patient_id` false otherwise primary= ) … -
